When compiling with W=1 the following warnings are triggered: drivers/input/serio/serio_raw.c: In function ‘serio_raw_connect’: drivers/input/serio/serio_raw.c:303:28: error: ‘%ld’ directive output may be truncated writing between 1 and 11 bytes into a region of size 7 [-Werror=format-truncation=] 303 | "serio_raw%ld", (long)atomic_inc_return(&serio_raw_no)); atomic_inc_return() returns an int, so there is no reason to cast it to long and print as such. Fix the issue by removing the cast, printing it as unsigned decimal, and expanding the name from 16 to 20 bytes to accommodate the largest possible port number.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
